Interviewing as a < 10th percentile candidate

So I was advised to apply to places mostly in the 25th-75th percentile for my GPA and MCAT unless I had some kind of "crazy story". However one school, a top 25, I was at the median for MCAT but less than 10th for GPA...but the secondary was free so literally the day of the secondary deadline (10/1) I decided to just throw in an app because why not. Well low and behold a short two weeks later (10/15) I received an interview unexpectedly for January. My question is now, how do I move forward... Interviewing as a <10th percentile candidate
